Application filed February 20, 1906. Serial No. 302,026.

To alt whom, it may concern:

Be it known that I ARTHUR R. MONETTE, a

citizen of the United States,residingat New I York city, in the county of New York and State of New York, haveinvented certain pose of dislodging dirt therefrom and keeping it clean.

It also has for its object to provide a streetsweeper which is simple, inexpensive, and

' durable in-construction, easy to operate, ef-

fective in use, and which will perform the work allotted to it in a thorough expeditious means for sprinkling the ground or pave- Inent whenever it is found to be necessary by the condition of the dust, means for automatically and simultaneously sweeping the street, collecting and elevating the sweepings into a suitable.refuse-receptacle, and means for raising said refuse-receptacle to such position thatv when turned upside down its contents will be dumpeddirectly into a cart or Wagon.

Referring to the drawings, Figure 1 is a side elevation, Figs. 2 and 3, bottom plan and side elevation, respectively, of the brush operating and vibrating mechanism on an enlarged scale; and Fig. 4 is a vertical longitudinal section, partly in elevation.

In the drawings, in which like numerals of reference denote like parts throughout the several views, 1 represents my improved streetsweeper, having a frame 2, front and rear axles 3 and 4, respectively, front steeringwheels. 5, mounted on the front axle 3, rear traction-wheels 6-, mounted on the rear axle 4. The main shaft 7 of the sweeper is ,rnounted in the sides 8 of the frame 2 and is provided gear-wheel 10 intermediate said ends, 11 being a sprocket-wheel mounted at-a proximately the center of said shaft 7, w ich is with a gear wheel 9 at each'end and a chain 12, with a suitable steam-engine or gasolene, electric, or other motor. A shaft 13, also mounted in the sides 8 of the frame 2, is provided with a gear-wheel 14 near each end, which mesh with the gear-wheels 9 on' the main shaft 7.

1 An arm 15 is mounted on each end of the shaft 13 and is provided with a slot 16 at its lower end to receive the ends of the shaft 17 of the rotary brush 18. On the'inner side of each arm 15, midway of its ends, a gearwheel 19 is mounted on a pin 20, and each of said gear wheels meshes with one of the gear-wheels 14 on the shaft 13 and with a gear-wheel 21 on each end of theshaft 17 of the rotary brush 18. Each of the pins has a lever 22 pivoted thereon, the lower end of each of, said levers being attached to the shaft 17 of the rotary brush and the upper end of each of the levers being pivotally connected to a'li'nk 23, which in turn is pivoted on a pin 24,- eccentrically mounted on a disk 25 on. each end of a shaft 26, said shaft being provided with a pinion 27, which me hes with a gear-wheel 10 on the main shaft 7, by which it is driven.

, A shaft 28,'1nounted at its opposite ends in the side 8 of the frame 2 of the sweeper, is provided with crank-arms 29, one end of each of said armsbeing connected to one of the arms 15 by means of springs 31, and the upper end 32 of each of the crank-ar1ns 29 I is connected to a rod 33, which in turn is connected to a hand-lever 34,'said lever being for the purpose of raising and lowering the rotary brush from the ground when not in use and the springs being for the purpose of regulating the'pressure of the sa1d brush-on the ground or pavement and allowing it to be readily lifted over any fixed obstruction.

The sweepings fromuthe rota brush 18 are delivered to an apron 35, whic 1 is pivoted to the lower end of an elevator 36 and supported by means of links 37, pivoted to the arms 15. H The elevator comprises a suitable cover or inclosing casing 38, provided with an endless conveyor-belt 39, running over pulleys. and having slats 40,- arranged at intervals across the same, said slats being provided with brushes 41 of any desired kind for the purrush upward and along the under side or bott'omof the elevator-casing 38.

At and just below the upper end of the operativelyc onnectedbymeans of asprockct- 1 elevator-casing a refuse receptacle or box is ose of conveyingthe swecpings from the placed, which is pivoted to the lower ends of arms 43, and the upper ends of said arms are motion to the shaft 44 through. the medium of the gear-wheel 45*. A suitable hand-lever 46 is pivoted to the cover 47 of the refuse-receptacle for the purpose of affording means whereby the said cover may be raised.

In order to providefor the sprinkling of the ground. or pavement to allay the dust, a liquidecontaining tank 48 is provided at the rear of the frame of the street-sweeper and has a filling-opening 49 and cover 50 at the top and an outlet or discharge pi e 51 depending from the bottoni, said pipe eing provided at its lower end with a nozzle or sprinkler 52 in the form of a straight pipe perforated from end to end and transversely disposed across the under side of 'the sweeper.

The rear traction-wheels 6 are driven and the street-sweeper propelled through the medium of a ear-wheel 53 on shaft 54, which meshes wit a pinion 55 on main shaft 7, a bevel gear pinion 56, which meshes with a bevel gear-wheel 57, mounted on the u per end of a shaft 58, and a bevel-gear 59, w ich meshes with a bevel-gear on the axle 4.

The elevator is operated by means of an endless belt or sprocket-chain 59, which op eratively connects a sprocket-wheel 59 on the shaft 54 with a sprocket-Wheel on the shaft 61 of the elevator. The number of vibrations relative to the number. of rotations of the rotary brush can be varied by changing the relative sizes of the gears 10 and 27, and the vibratory movement of said brush is independent of the raising-land lowering and rotary movement of the same. The propelling of the street-sweeper, the rotary and vibratory movement of the brush, the collecting and elevating of the sweeping, and depositing them in a suitable receptacle is done simultaneously.

In 0 eration the main shaft is caused to rotate y means of a suitable steam-engine or motor, which communicates with and drives the gear-wheels 9, which communicate motion to the gear-wheels 14 and from the gearwheels 14 to the gear-wheels 19 and 21, said gear-wheels 21 imparting a rotary movement to the brush-shaft, and at the same time the gear-wheel 10 communicates motion through the pinion 27 to the shaft 26 and from the disks 25 and pins 24 to the links 23, and from the links 23 to a lever 22 to the rotary brushshaft 17 and causes the shaft to vibrate up and down in slots 16 in the arms 15, and as the brush collects and delivers the .swecpings to the elevator the elevator elevates said sweepings and delivers them to the refuse-receptacle 42. The lnnnl-wheel 36 is then operated, which causes the arms 4-3 to swing upward and raise the refuse-receptaele to such position that when turned upside down the sweepings contained therein will be dumped into a wagon, cart, or other remap-- tacle, when said swecpings may be carted away to a dump or other suitable place.

Although the vibratorymovement of the brush is mainly for the purpose of keeping said brush clean, yet it also assists in throw ing or delivering the sweepings upon. the apron, said vibratory movement being pro- .duced by mounting pins 24 occentrically on the disks 25 on each side of the shaft 26, so that when said shaft is revolved it will operate the levers 22 and cause their lower ends to move up and down on the are of a circle struck from the center of the pins 20 in the slots 16 of the frames 15.

I do not desire to be underst ood as limiting myself to the specific details of construction and arrangement as herein described and illustrated, as it is manifest that \mriations and modifications maybe made in the fea tures of construction and arrangement on the adaptation of the device to various conditions of use without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variations and modifications as properly fall Within the scope of my inventim'i and the terms of the following claims.
